Havana has a dilapidated ruined beauty - decaying grandeur alongside squalor with a string atmosphere of Africa and Old Spain. Despite the political turmoil of Cuba's last 30 years, its people remain among the most imaginative and fascinating in the world. Under the dictatorship of Castro, Cuba has become a highly regulated state to say the least.

The film goes beneath the skin of this legendary city, particularly through its extraordinarily rich music which enables the people to express their true attitudes and feelings. It also visits Little Havana in Miami, 90 miles away, home to some of the one million exiles to have left Cuba in the last 30 years.

The non-synch audio track consists of conversations with and among those faces: dreams, regrets, arguments, affection, observations, opinions.
